Lamprinakou et al. [1]} have introduced a novel epidemic model using a latent Hawkes process with temporal covariates for the infections and a probability distribution with a mean driven by the underlying Hawkes process for the reported infection cases. A Kernel Density Particle Filter (KDPF) [2]}, [3]} is proposed for inference of both latent cases and instantaneous reproduction number and for predicting the new infections over short time horizons. Modelling the infections via a Hawkes process allows us to estimate by whom an infected individual was infected [4]}.
